Teen Away repels teenagers with high frequency sound waves
Philadelphia officials have turned to a controversial device to stop late-night loitering and vandalism by teens : a sonic device called the Mosquito. It's a beige speaker unit that emits a piercing, high-frequency buzzing sound. The City of Brotherly Love has been using the Mosquito for the past two years to keep teens away from city parks and recreation centers at night. At 10 p. It's main setting is audible to individuals from age 13 to 25 years old, according to the company that makes it, Moving Sound Technologies. As the cells in our ears age, they typically lose the ability to pick up higher sound frequencies.
